If a non-mythic creature within 30 feet of you uses a spell or spell-like ability, you can expend one use of mythic power to make a ranged attack against that creature as an attack of opportunity (even if the creature wouldn’t normally provoke attacks of opportunity). You must have a ranged weapon in hand or have a free hand and the non-mythic Quick Draw feat to use this ability. You can use this ability against a mythic creature by expending two uses of mythic power.
